The statements below can be used to prove that the triangles are similar. On a coordinate plane, right triangles A B C and X Y Z are shown. Y Z is 3 units long and B C is 6 units long. StartFraction A B Over X Y EndFraction = StartFraction 4 Over 2 EndFraction ? StartFraction A C Over X Z EndFraction = StartFraction StartRoot 52 EndRoot Over StartRoot 13 EndRoot EndFraction △ABC ~ △XYZ by the SSS similarity theorem. Which mathematical statement is missing? StartFraction Y Z Over B C = StartFraction 6 Over 3 EndFraction ∠B ≅ ∠Y StartFraction B C Over Y Z EndFraction = StartFraction 6 Over 3 EndFraction ∠B ≅ ∠Z
cost of tshirt is 40
50=x + y
let X -cost of shirt
Y -cost of tie
X = Y+30
50=Y + 30 + Y
80= 2 Y
Let...x be the number of boysx + 26 be the number of girls
Getting the number of boys.
Now, let's get the number of girls by substituting.
The word phrase "Two-thirds the difference of a and b" can be written as...
